Preliminary Announcement:
Solicitation of entities to implementwith subsidies the “Validation oftechnologies for contaminated watermanagement” project in the FY2013
Supplementary Budget

MRI News

The Mitsubishi Research Institute, Inc., having been selected by the Agency for
Natural Resources and Energy (ANRE, METI, Japan), is now executing the tasks of
the Project Management Office for the “Project on Decommissioning andContaminated Water Management.” In this project, based on the “Grant Policy for
Subsidy for the Project on Decommissioning and Contaminated Water Management,”
we are assisting activities in support of the development of technologies that will be
useful in decommissioning and contaminated water management. Through this, weaim to improve the level of science and technology and to advance decommissioning
and contaminated water management smoothly in Japan.
At this time we are proceeding with the RFP(Request for Proposal) for entities toreceive subsidies and implement the “Validation of technologies for contaminatedwater management” project in the FY2013 Supplementary Budget. With this news
release, we are providing a preliminary announcement of the RFP. More detailed
information shall be provided separately on our website in the near future.

Purpose of this project

As for the countermeasures for contaminated water arising in Units 1 to 4 at theFukushima Daiichi Nuclear Power Station of Tokyo Electric Power Company(hereinafter referred to as the “Fukushima Daiichi NPS”), the Committee on
Countermeasures for Contaminated Water Treatment released “Preventative andMultilayered Measures for Contaminated Water Treatment at the Fukushima Daiichi
Nuclear Power Station of Tokyo Electric Power Company - Through completeness ofcomprehensive risk management -“ (Summary, Text) on December 10, 2013, andbased on this report, the Government published the “Additional Measures forDecommissioning and Contaminated Water Issues at TEPCO’s Fukushima DaiichiNPS”(Summary).
The Additional Measures are expected to be highly effective but among thetechnologies which require confirmation and verification for their application, it wasdecided to carry out technology verification of those techniques that have a highdegree of technical difficulty. In this project, we intend to implement validation of thetechnologies listed in Section 2, “RFP topics.” Additional RFP for other technologies
is under consideration.

2. RFP topics(1) Demonstration Project for Seawater Purification Technologies
At present, although the densities of radioactive substances outside of the port or at
the port entrance of the Fukushima Daiichi NPS remain at a low level, in some areas
in front of the water intakes of Units 1 to 4 in the port, the density has not decreased
below a certain level. Considering this situation, a verification test shall be carried out
to validate the performance of purification technologies for removing mainlyradioactive cesium, radioactive strontium, etc. from seawater.
(2) Demonstration Project for Technologies for Capturing Radioactive Substancesfrom Soil
At the Fukushima Daiichi NPS, considering the leakage of contaminated water fromthe tanks in the past, a verification test shall be carried out to validate the performance2

of capturing technologies for removing radioactive substances (mainly radioactivestrontium) from soil whose density of chloride ions exceeds a certain level (above 200ppm).
(3) Demonstration Project of Technologies for the Decontamination of Contaminated
Water Tanks
On the site of the Fukushima Daiichi NPS, bolted tanks will be replaced withwelded-joint tanks. In order to reduce the radiation exposure of workers engaged indismantling work, it is necessary to validate the performance of the decontamination
methods of bolted tanks, whose inside structure is complex. In the decontamination ofbolted tanks, the contaminated water stored inside the tanks will be discharged, andthe decontamination work will be done as a preparatory step of their dismantlement.
(4) Demonstration Project for Unmanned Boring Technologies
At the Fukushima Daiichi NPS, borings will be indispensable, as before. In order toreduce the radiation exposure of workers engaged in boring activities, a verification
test shall be carried out to validate the performance of unmanned boring technologies
under conditions of high-dose radiation.
